Combine crumbs and nuts with brown sugar; mix in melted butter until well moistened. Pat into a 7-inch springform pan.

Beat cream cheese and sugar together until smooth. Add the eggs, cream, vanilla, and flour; beat for 3 to 4 minutes at medium speed of a hand-held electric mixer. Pour into the prepared crust and place on a rack or ring of aluminum foil (to keep it off the bottom of the pot) in a 5-quart Crock Pot (large enough to fit the springform pan). Cover and cook on high for 2 1/2 to 3 hours. Turn off and leave for 1 to 2 hours, until cool enough to remove. Cool completely and remove the sides of the pan. Garnish with pecan halves if desired.

Combine Italian dressing and water. Pour over chicken. Cook on LOW for 8 hours, or HIGH for 4 hours (until chicken is cooked through).

Remove chicken from the slow cooker and shred. Leave the liquid stock in the slow cooker.

Mix together soup and cream cheese. Pour cream cheese mixture into the slow cooker and mix with the chicken stock. Stir broccoli into the slow cooker mixture. Add chicken back to the slow cooker and mix well.

Turn the slow cooker on HIGH and cook until heated through (about 30 minutes).
